Authors: E.M. Standish, X.X. Newhall, J.G. Williams & W.M. Folkner Copyright @1997 The Jet Propulsion laboratory, California Institute of Technology The JPL Planetary and Lunar Ephemerides on CD-ROM contains three different Jet Propulsion Laboratory Planetary and Lunar Ephemerides (DE200, DE405, and DE406) along with associated reading and interpolating routines. These allow a competent user to obtain the rectangular coordinates of the sun, moon, and nine major planets by means of a subroutine written in standard FORTRAN. The data and programs should be viewed by the potential user as a "tool box" for one skilled in computer programming and knowledgeable about astronomical computing. DE200: (includes nutations but not librations) JED 2305424.5 (1599 DEC 09) to JED 2513360.5 (2169 MAR 31)This ephemeris has been the basis of the Astronomical Almanac since 1984. It is based upon the dynamical equator and equinox of J2000 (see Standish, 1982 and Standish, 1990). DE405: (includes both n
